The domain of the function is all the values from which the functio can be mapped: here it's between 0 and <span>76,867 -depending on how many people come
</span>
The range is all the values that the function can have.So here it's from 0, when noone is coming, to 76867*161=12377036
the Answer is irrational number
12 the answer is 12 I know it
Answer:
7
Step-by-step explanation:
σ = 4 ; μ =?
8.52 to the left of X
.
P(X < 8.52) = 64.8%
P(X < 8.52) = 0.648
Using the Z relation :
(x - μ) / σ
P(Z < (8.52 - μ) / 4)) = 0.648
The Z value of 0.648 of the lower tail is equal to 0.38 (Z probability calculator)
Z = 8.52 - μ / 4
0.38 = 8.52 - μ / 4
0.38 * 4 = 8.52 - μ
1.52 = 8.52 - μ
μ = 8.52 - 1.52
μ = 7
